ETHYL PETROL

Some motorists may feel that they have not noticed any marked improvement in the performance of their cars when changing from an ordinary petrol to a Red Ethyl super spirit. This may be partly due to the fact that their first fill of Ethyl has been added to a tank already containing, say, a couple of gallons of ordinary petrol, and that the Ethyl motor spirit has been diluted in consequence. However, the full advantages of a spirit which has a very high anti-knock rating, such as an Ethyl spirit, can only be obtained from an engine that has been tuned to suit this modern type of motor spirit. The first thing to do is to get your service-man to advance the spark slightlv, and in some cases it is advisable also to have the carburettor adjusted to a “leaner” setting. These adjustments, which only take a few minutes, particularly the advancing of the spark, will result in smoother and cooler running and increased mileage. The increase in power will also be most marked. As there is a certain amount of teaching and technical knowledge necessary to obtain the best results, it is advisable to get your regular service-man to make these adjustments.
